To reveal the complicated stress state of masonry structure in project and the effect of normal stress on shearing behavior,failure form and shearing strength,the shearing strength was obtained through experiments on 54 pieces of minitype sand-lime autoclaved aerated concrete(AAC) masonry subjected to different normal stress.
为了解砌体结构在实际工程中所处的剪压复合的复杂受力状态,作用在砌体上的正应力对砌体的抗剪性能、砌体的剪切破坏形态及其对砌体抗剪强度的影响,对54个小型灰砂蒸压加气混凝土砌体进行静力抗剪试验,通过施加不同的正应力得到相应的抗剪强度;分析其破坏机理,归纳得出剪摩、剪压、斜压等破坏形态,并与砖砌体的破坏形态进行比较;根据试验结果回归分析得到灰砂蒸压加气混凝土砌体的静力剪压相关性曲线,与砖砌体的剪压相关性曲线进行对比分析,得到两者的异同;在静力剪压相关性曲线的基础上,依据变摩擦系数的剪摩理论,提出灰砂蒸压加气混凝土砌体静力抗剪强度的建议公式,并对摩擦系数进行了简化。
Although autoclaved aerated concrete is applied widely,the walls built by the blocks are easy to entangle in common quality defects owing to neglecting monitor of moisture content,which has a strong impact on its market reputation.
蒸压加气混凝土应用虽广泛,由于忽视监控含水率,所砌墙体极易产生质量通病,严重影响到市场声誉。
